| Descripción: | Background: The Chilean government implemented the first phase of a comprehensive marketing policy in 2016, restricting child-directed marketing of products high in energy, total sugars, sodium or saturated fat (hereafter “high-in”). Objectives: To examine the role that high-in TV food advertising had in the effect of the policy on consumption of high-in products between 2016 and 2017. Methods: Dietary data were obtained from 24-hour diet recall measured in 2016 (n = 940) and 2017 (n = 853), pre- and post-policy, from a cohort of 4 to 6 years children. Television use was linked to analyses of food advertisements to derive individual-level estimates of exposure to advertising. A multilevel mediation analysis examined direct and indirect effects of the policy through advertising exposure. Results: Children's high-in food consumption and advertising exposure declined significantly from 2016 to 2017 (P < .01). Consumption changes were not significantly mediated by changes in advertising exposure, which might suggest other elements of the Chilean Law potentially driving decreases in consumption to a greater extent than TV ads. Conclusions: Preschoolers' exposure to high-in advertising and consumption of highin products decreased post-policy. Further research is needed to understand how marketing changes will relate to dietary changes after full implementation of the law and in the long term. |
